In the movies I've seen that depict battle scenes from hundreds of years ago, every army has numerous soldiers whose job it is to carry festive flags and pennants. If this is an accurate depiction of history, what does it mean? That powerful symbols were crucial to inspiring the troops' heroic efforts? That touches of color and beauty lifted their morale? That they were more inclined to do their best if inspired to imagine they were participating in an epic story? Whether or not my theories apply to what actually happened back then, they apply to you now. As you go forth to fight for what you believe in, bring your equivalent of an evocative emblem.
